I’m very impressed. work of yours is magnificent and imho must be finished, polished and merged. I’m going to play with it a bit, check out what it can do and what it can’t yet, and I’m totally wish to contribute my time. LPV is a nogo (imho: directional light only, 1 bounce? It’s not enough), VGXI is dead (? latest version supported is 4.6) and Enlighten costs like a spacetrip and, basically, unavailable to us, humble indie.
I don’t have any experience in UE4, but I have years of software development exp and even some patches in Kernel, so I think I may be helpful. Going to look through your commits week. Also I’ve made a skype contact request.
